Ankle sprain (broken foot) is generally caused by external forces that tear and damage the muscles and ligaments of the ankle, causing capillary bleeding and local tissue edema, with pain and swelling as the main manifestation. If the ankle is sprained, the muscles are damaged and the veins are injured with it. Qi and blood stagnation can lead to hematoma, which can cause pain and dysfunction. If the treatment is not timely or improper, it can cause local swelling, which is difficult to eliminate and can even cause tissue adhesions. In the early stage of ankle sprain, i.e. within 24 hours, ice and pressure should be applied to reduce capillary bleeding and tissue fluid exudation, and hot compresses and compression should not be used to prevent injury and bleeding. After the active bleeding period has passed, methods to activate blood circulation and remove blood stasis can be used, such as acupuncture and acupuncture to release blood. Stabbing and releasing blood can make the blood stasis out, dispel cold and relieve pain, so that the meridians can be smooth. At the later stage of the injury, when the swelling is not obvious, massage treatment can be used. At the same time, functional exercises of the foot and ankle, such as dorsiflexion and flexion exercises of the foot, can be taken. The recovery of ankle sprain is not only to eliminate swelling and pain, but also to cause adhesions in the local tissues, functional disorders, and even habitual sprains and traumatic arthritis in the ankle if the recovery is not in place.
